APatented Dec, 3, itljl.

Application filed April 11?, 1918.` Serial No. 228,295.'

To all whom t may concern.

Be it known that l, ROLAND E. Hownnn; a citizen of the United States', residing at 'orcesten in the county of `Worcester and State of Massachusetts, have invented a new and useful Mask, or whichv the following is a specification.

This invention relates to a mask or blinder, and the principal objects thereof are to provide a construction which can be adjusted to it the head or' the wearer, but cannot readily be removed without destroying it so that it cannot be used a second time, thus securing asanitary product that cannot cjarry disease or the like; to provide a construction ot simple form which will be inexpensive to make; and to provide improvements by which the mask can be adjusted and yet not be removable, and other features of construction aswill appear.

Reference is to be had to the accompanyin drawings, in whichigure l is a front viewY of a mask constructed in acoordance with this invention, showing its two strings extending there.

' from Fig. 2 is a plan showing it in position to lit the head or the wearer;

Fig'. 3 is an eleva-tion' or the adjustable fastening device;

Fig. i is a sectional view et the same, and

Fig. 5 is a view of a portion of the device showingg how the mask is intended to be detached from the head of the wearer.

The principal use intended for .this in vention is to make masks or blinders tor use in initiatory exercises and the like. Under present conditions these masks are used over and over again and can easily carry diseases, particularly diseases of the eyes. This invention is designed to prevent the reuse of a mask, and to provide a construction which will be cheap enough to permit of its being thrown away after being used once.

of the head andi have their ends attached tocapa string. rlhis is to permit of this tab being pulled outwardly solas to tear it from the mask through said perforations, taking the strin with it, thus rendering the mask inle of being used .again when it is ren'ioved. 'i f For the purpose of connecting thestrings together at the back, one of them is made.

plain and the other is provided with a connocting device QOpreferably of sheet metal and having1 one or more tongues 2l of exible sheet metal ,preferably integral with the main portion thereof extending inwardly at a slant. This slant is toward the mask so that the end of theother string can be forced under these tongues and pulled up as tightznay he desired'in order to securely tasten the mask on the head oi the wearer, but if it is desired to pull 'the strings apart to detach 'the n ask the tongues by their resiliency will engage the loose string and prevent its being .f rawn back in that n1anner. ln order toV make this action more efii'cient, thetongues can be provided with sharp serra tions on their edges it desired, shown. The metallic member 20' is provided with rprqections 23 at its ends for fastening it to the stri 11.9112.

In the use of the in position and the strings brought around the back ot the head oi' the wearer, and the end of the string ll is forced in under the tongues 2l. and its end drawn clear through the fastening; device 20. lt is then pulled up tight so that the mask will fit on the head and is then worn for any desired length of time. lfhen it is desired to remove the mask a pull on either stringr will not accomplish this purpose except by breaking tne string, and itis preferable to device the mask is put of cheap sheet material and is rendered sanitary by preventing its reuse.

Although I have illustrated and described only a single form of the invention, I am aware of the fact that `modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction herein shown and described, but what I do claim is l. As an article of manufacture, a mask or blinder eonsistingof a piece of sheet material havingstrings extendingt'rom its opposite ends and a connection between one oit' said strings and the mask proper more readily' frangible than the string or mask to localize the line of detachment.

As an article of manufacture, a mask or yblinder consisting of a. piece 0f sheet material having strings extending from its opposite ends formed of the same material and permanently connected therewith, and means on one of said strings for recei ing the other and allowing it to pass through in one direction so as to tighten up the strings on the head, of thefwearer, but. preventing' its. heilig moved in the opposite direction.

3. As an article of manufacture, a mask or blinder having strings extending from its 3e opposite ends, and means o'n one of said strings for receiving the other and allowing it to pass through so as to tighten up the strings on the head of the wearer, but preventing its `being moved in the opposite cli 35 reetion. n i e l. As an articleI of manufacture, a mask-\ or blinder having strings extending from it. ends, and a series of perforations arranged in rows on the two sides of one string soll@ that that string can loe readily detached from the mask to remove the mask and Apren vent its reuse.

5. As an article of manufacture, amask or blinder having strings extending from its ends, and having a series of perforations arranged in rows on the two sides of one string so that that string can be readily detached from the mask to prevent the mask being used over again, and a tab at the end 50 ot' said string to facilitate tearing the string away t'rom the mask.

In testimony whereof I a iii xed my signature.
